実験手順

A solution of 3,4-difluoro-2-[(2-fluoro-4-iodophenyl)amino]benzoic acid (201 mg, 0.512 mmol), prepared using procedures similar to those described in U.S. Pat. No. 7,019,033, 3-(2-aminopyrimidin-4-yl)azetidin-3-ol (87 mg, 0.52 mmol), benzotriazol-1-yl-oxy-tris(pyrrolidino)phosphonium hexafluorophosphate (293 mg, 0.563 mmol) and N,N-diisopropylethylamine (270 uL, 2.82 mmol) in N,N-dimethylformamide (2 mL) was stirred at room temperature for 20 h. The mixture was partitioned between ethyl acetate and saturated sodium bicarbonate. The organic layer was separated and washed with brine, dried over sodium sulfate, filtered and the filtrate concentrated in vacuo. The residue was purified by reverse phase HPLC to afford the title compound 3-(2-aminopyrimidin-4-yl)-1-({3,4-difluoro-2-[(2-fluoro-4-iodophenyl)amino]phenyl}carbonyl)azetidin-3-ol (22 mg, 7%). 1H NMR (400 MHz, CD3OD): 8.23-8.20 (d, 1H), 7.48-7.43 (d, 1H), 7.35-7.32 (m, 2H), 7.09-7.00 (m, 1H), 6.88-6.84 (d, 1H), 6.70-6.63 (t, 1H), 4.59-4.54 (d, 1H), 4.45-4.40 (d, 1H), 4.23-4.18 (d, 1H), 3.04-3.99 (t, 1H); MS (EI) for C20H15F3IN5O2: 542 (MH+).
